The type of triangle it is C. equilateral.
Since the triangle has sides measuring 4 cm, 4 cm and 4 cm, all its sides are equal.
Also, two of its angles measure 60°.
We need to determine the third angle.
Let the third angle be x.
So, 60° + 60° + x = 180° (Sum of angles in a triangle)
120° + x = 180°
x = 180° - 120°
x = 60°
Since the third angle is 60°, it implies that all its angles are 60°.
So, a triangle haing all its angles as 60° and sides equal is an equilateral triangle.
So, the type of triangle it is C. equilateral.
